A nurse is collecting data from a newborn who has respiratory distress syndrome and is experiencing respiratory acidosis. Which of the following risk factors predisposes the newborn to respiratory difficulties?
Small for gestational age.
Maternal history of asthma.
Ventricular septal defect.
Cesarean birth.
The Correct Answer is A
Choice A reason:
Small for gestational age (SGA) newborns are at risk for respiratory distress syndrome (RDS) and respiratory acidosis because they have immature lungs that produce less surfactant, which is needed to keep the alveoli open and prevent atelectasis. SGA newborns also have less glycogen stores, which can lead to hypoglycemia and impaired oxygen delivery to the tissues.
Choice B reason:
Maternal history of asthma is not a risk factor for RDS or respiratory acidosis in the newborn. Asthma is a chronic inflammatory disorder of the airways that affects the mother, not the fetus. Maternal asthma can cause complications such as preterm labor, preeclampsia, or intrauterine growth restriction, but it does not directly affect the fetal lung development or function.
Choice C reason:
Ventricular septal defect (VSD) is a congenital heart defect that causes a hole in the wall between the ventricles of the heart. This can result in increased pulmonary blood flow and pressure, which can lead to pulmonary edema and heart failure in the newborn. However, VSD does not cause RDS or respiratory acidosis, which are related to lung maturity and surfactant production.
Choice D reason:
Cesarean birth is not a risk factor for RDS or respiratory acidosis in the newborn. Cesarean birth can increase the risk of transient tachypnea of the newborn (TTN), which is caused by delayed absorption of fetal lung fluid. TTN usually resolves within 24 to 48 hours and does not cause a significant acid-base imbalance in the newborn.

Correct Answer is ["A","B","C","E"]
Explanation
A. Discard unused formula in used bottle after 2 hours:Once a baby has started drinking from a bottle, bacteria from the baby’s mouth can contaminate the formula. Any leftover formula should be discarded after 2 hours to prevent bacterial growth and reduce the risk of infection.
B. Never prop a bottle:Propping a bottle can lead to choking, ear infections, and dental issues (such as baby bottle tooth decay). Babies should always be held upright during feedings.
C. Formula is available in three forms:Infant formula is available in three types:Ready-to-feed (no mixing needed),Liquid concentrate (mix with water),Powdered formula (mix with water).
E. Store prepared bottles in the refrigerator:If formula is prepared in advance, it must be stored in the refrigerator (≤ 4°C or 40°F) and used within 24 hours to prevent bacterial growth.
Incorrect Answer:
D. Warm the bottle in the microwave:Microwaving heats unevenly, creating hot spots that can burn the baby’s mouth. Instead, warm bottles by placing them in warm water for a few minutes and always test the temperature on the wrist before feeding.
Correct Answer is B
Explanation
Choice A reason:
Administering methylergometrine to the client is not the first action the nurse should take. Methylergometrine is a medication that stimulates uterine contractions and can help reduce postpartum bleeding. However, it can also cause hypertension and should be used with caution in clients with high blood pressure. Furthermore, the nurse should first identify and address the cause of the boggy and deviated fundus before giving any medication.
Choice B reason:
Assisting the client to void is the first action the nurse should take. A full bladder can displace the uterus and prevent it from contracting properly, leading to uterine atony and bleeding.
The nurse should help the client empty her bladder by encouraging her to use the bathroom, providing privacy, running water, or using a bedpan. This can help the uterus return to its normal position and tone.
Choice C reason:
Inserting an indwelling urinary catheter is not the first action the nurse should take. A urinary catheter can be used to drain the bladder if the client is unable to void or has a large amount of residual urine. However, it can also increase the risk of infection and trauma to the urethra
and bladder. The nurse should first try noninvasive methods to help the client void, such as those mentioned in choice B.
Choice D reason:
Obtaining a stat hemoglobin level is not the first action the nurse should take. A hemoglobin level can indicate the extent of blood loss and the need for transfusion or other interventions. However, it is not a priority over restoring uterine tone and preventing further bleeding. The nurse should first assist the client to void and then massage the fundus if it remains boggy.
